I just started over. I always save RIGHT before I get out of the sewers so I don't have to do the dumb crap in the beginning, I just load that save and edit everything when I exit. I hate that grave robbing friend supplying the Copious Coinpurse. I hate him, so when I killed him, I entered his house, dragged his stuff into a pile, and shot it with Flares. Repeatedly. Then I stole it all.
Also, If you didn't know this, paintbrushes have NO physics. None. Drop one in the air, jump on it, drop another one, and make a staircase. I get to the top of the watchtowers, houses, the palace, that Arcane University place, and all.
